The Energy Transition Index ranks 118 countries on their journey toward clean, secure and sustainable energy. Among them, three countries stand out for their innovation and technological leadership.
China leads in clean energy tech and start-ups
China holds the largest share of global energy patents and was home to about 1,200 of the world’s 4,000 new energy start-ups in 2023. It produces 70 percent of all electric vehicles globally and dominates battery manufacturing.
Germany excels in renewables and green transport
Germany is a pioneer in solar and offshore wind, with 39 percent of its power generation now coming from renewable sources. It also leads in energy-related patents, especially in energy storage and electric mobility.
Brazil innovates with biofuels
Brazil is an emerging-market leader in clean energy innovation. It is a top producer of biodiesel and is now developing a biofuel that could fully replace fossil diesel, marking a major step toward energy sustainability.
Why innovation matters for the energy transition
The Energy Transition Index also scores countries on investment, energy security and equity. Innovation plays a crucial role in accelerating clean energy solutions that are accessible and resilient.
Watch the video to explore how these countries are setting the pace for a global clean energy future.
